The casing, however,

constitutes y,a pendulum lever as stated above,

and when a load isput'uponthe scale pan it exerts a pull u on the casing through "the link and brac et above. described which swings the casing about the arbor 11 until its Acenter of gravity has been so displaced that the weight of the casing under the leverage employed' counterbalanc'es or offsets the load on the scale an. Fig. 4 shows the casing swung upwar by placing a weightin the'scale pan' which, as illustrated, equals the reading capacity of the scale. ."As the-casing swings about its point of suspension the pinion 29 travels along the stationary rack `6 Whichis concentric with the point of suspension of the casing, andthe hand is thereby revolved -to.indicate the weight on the scalepan, the

dashpot in the meantime reventing violent movements of the parts. twill thus be seen -l that the casing and its contained parts constitute the pendulum of the scale thus dispensing with a distinct and separate pexalulum andA furnishing a` scale which may be Areadily shipped'or subjected to rough treatmentV without damage. f

Inthe construction shown in Fig. 5, the

casing isagan used; as the pendulum weight for o setting the weight o the load, though the action is somewhat different from that of I the above described scale.

In this case the castin which comprises the rack segment 6 .is itse f hung upon knife edge bearings 33, 34, and constitutes the pendulum. Said knifefedge bearings are received in the eyes 'ofa loop 35 which may be suspended in any coperates with airack 6 l A dashpot 31 attachedl to some stationary y the parts. It will suitable manner, and the casting is enlarged at 36 and cross-bored to receive the arbor 37 of the casing which is thus pivotally suspended from the casting.v To the arm 38,

formed integral with the casting, is attached the link 39 which, as shown, is connected at 'its lower end to a beam 40 of the scale,

though obviousl if desired, a lscale pan could be suspen ed from the link 39. The casing, as in the earlierdescribed form of thescale, carries a dial with which a hand 28 mounted on a spindle 27. coperates and the last-named element also carries as in the other form of the device, a Pinion 29', which part of. the scale re lates the -movement of f readily seen that the castingsuspended by the knife edge bearing 34 constitutes the pendulum, of whlch the pivoted casing is thewei ht and that draft.

upon the arm 38swings t e casting and the suspended casing, the latter, however, maintaining its position with the zero marking uppermost by `swinging upon its arbor. As the .casting is deflected from its normal posiof the casting.

tion the `4rack 6 turns the pinion S29y and shifts the indicating hand 28 to a position indicating the load u on the scale pan.

'.It will be observe `thatin general principle of operation the form of scale shown in Fig. 6 resembles that of Fig. 5, though it differs therefrom in "some details which will be referred to later.` The casing and dial are substantially identical with'the similar ele- -ments ofthe scale' just described. A pendulllm member 41 is pivoted tothe casing atf37 and provided with a rack segment 6'engaging a gear 29 upon the spindle of said indiv cator hand. The pendulum member 41 is 35 which is adapted to be suspended from any suitable support. VSaid'loop islfo'rmed upon its opposite-ends with enlargements 42 -whichv are perforated to receive the knife edges '34" `above-mentioned. The latter, as shown moreparticularly in Fig... 7, 4are formed on a cylindrical trunnion member 43 suspended by knife edges 34? from a loopto which' is rigidly' secured the upper endiof l the pendulum-member 41,. the latter ybeing transverselyf bored for .this purpose.. The head 44 of saidvpendulum member in which the trunnionis secured Lis bifurcated or slotted at 46 to :receive an .arm 46 .which is Y angularly adjustable around the trunnion. From this arm the loop 47 is suspended Aand the link 48 connects the latter with the load receiver of they scale, directly inthe casepf a hanging scale and indirectly in thecase of a` beam scale.' Acorrectvadjustment between the pendulum member 41 and said Aarmv is secured. by the fllowingdevice. The endulum member is formed or provided wlth oppositelyextending ears 49,.'49, which vare` perforated and tappedto receive screws 50, 50, the ends of which bear upon seatsl r5,1, 51

By easing one screw 'andtghtening up on theother yany adjustment `between ,the parts withinthe `narrow limits required may be obtained. link 52' is pivoted atj 53 to .the casing. and at 54 to the link 48 to fproperly ,guide and maintainthe position ko 'theflatter and the dashpot 31 1nA this construction issecured to the casing in a normally inclined position and its pis- V`'ton y32 .connectedv by a rodI 33"with said .ias
